tailoring compared with the cases of the preceding species. Of the 

 genus Lithocolletis but one species, the variable L. spinicolella, feeds 

 on this plant; it mines the under side of the leaves, and makes but a 

 small mine : the brown blotches on the surface of the leaves sometimes 

 inform us that Cemiostoma scitella has not disdained to feed upon 

 the sloe, though it is more frequently observed upon apple and 

 hawthorn. Of the genus Nepticula the two now well-known species, 

 N. plagicolella and N. Prunetorum, are all that we have at present 

 discovered. 



Prunus pad us. Bird Cherry. 

 The especial food-plant of Hyponomeuta Padi, but not that I am 

 awarelnteresting to us in any other way. 



Prunus Lauro-cerasus. Laurel. 

 Though not generally attacked by larvae, it is sometimes ; I once 

 saw a bush nearly stripped of its leaves by the larvae of Episema 

 caeruleocephala, and Mr. D' Urban informs me that he has bred both 

 this insect and Porthesia chrysorrhaea from larvae fed exclusively on 

 this plant ; the perfect insect must have been as hard to kill as 

 Mithridates. 



Spiraea Ulmaria. Meadow Sweet. 

 How the mere mention of the name of this plant reminds us of 

 hay-fields and long summer's evenings, and rambles by the banks of 

 streams. My Dipterist friends are of course well aware that there is 

 a Dip. larva very abundant in the leaves of this plant in July : a 

 Coleophora larva has been found on this plant, the case of which 

 resembles the case of the elm-feeding C. fuscedinella, but the perfect 

 insect was not bred, and so we only suspect that they should be 

 referred to that species. Strange that a plant so plentiful should not 

 be more patronised by Lepidopterous larvae. 



Spiraea Filipendula. Dropwort. 

 Abundant at Mickleham Downs, and on other similar localities, 

 but not at present known as the food of any Lepidopterous larva. 



Geum urbanum. Wood Avens. 



A common but inconspicuous plant in hedge-boltoms and moist 



shady places ; the flower so soon falls to pieces that it rarely attracts 



our attention, but the burr-like seeds are more conspicuous ; the leaves
